An Intelligent Traffic Light System Based on Piezo- Electric Sensors

Abstract

(A) Objective –The project aim is to make a traffic light that will solve the traffic problem on crossroads by detecting movement of vehicle with the help of piezoelectric sensors and reducing the open time for that lane in which the traffic is low and increasing the green light open time for that lane in which there is a dense traffic. (B) Method- This smart traffic light project required sensor that will sense the vehicle movement and the number or density of vehicle on a certain lane of a crossroad and send logical messages to the micro command that will change the time for opening the green light for a certain lane of crossroad (C) Finding- In current years traffic is automatic and changing of the green light opening time for lane on crossroad is one by one and opening time for all the lane is same and many crossroad traffic are controlled by traffic police .The reliability of those method are less and also its take a men power to operate the traffic . This smart traffic light does not conserve energy for all the operations because the piezoelectric sensor that we are using that will give the power for operating all the systems  It does not take external energy for operating all the operation  The aim of the smart traffic light is to reduce the traffic problems  This project will save the time In my project I used piezoelectric material, which is cost effective. For the communication purpose we have used Zigbee communication is used to communicate between the traffic light and sensor which will calculate the parameter and store the information about the vehicle. Improvement- The entire setup can be connected through the internet of thing (IOT) for process like data extraction. Which is particularly useful for place like four way junctions etc.
